This article outlines a novel method for rapidly acquiring temperature-dependent hot corrosion data for superalloys in the temperature range 6001000 °C. The technique is illustrated for the aerospace superalloy, CMSX-4, generating results that localise peak hot corrosion damage at 725 °C (Type II) and 900 °C (Type I).

Jiangsu Longda Superalloy Co., Ltd Mining & Metals , 204 followers Nickel based, Cobalt based, Iron based superalloy bar, rod and billets, Copper nickel alloy and nickel Kevin Yoon - Northwestern University Center for Atom Dec 06, 2005 · During my graduate study at Northwestern University, Ive been working on Ni-based superalloys, from model Ni-Cr-Al alloys to complex commercial superalloy René N6. By investigating the base Ni-Cr-Al ternary alloy, and then add microalloying elements, such as Ta, W, Re, and Ru, we seek to pinpoint the synergistic effects of each additional

LOW CYCLE FATIGUE BEHAVIOR AND LIFE PREDICTION

305-380, Korea [email protected] Co-base superalloys have been applied in the stationary components of gas turbine owing to their excellent high temperature properties. Low cycle fatigue data on ECY-768 reported in a for power generation are mostly made of cobalt based superalloys such as ECY-768 alloy. NASA Technical Reports Server (NTRS)Dual alloy combinations of iron rich Alloy 901 with nickel base superalloys Rene 95, Astroloy, or MERL 76 were not isostatically pressed from prealloyed powders. Individual alloys, alloy mixtures, and layered alloy combinations were given the heat treatments specified for their use in turbine disks or appropriate for Alloy 901.

New magnesium alloy is world's strongest and lightest

Jan 09, 2015 · New Magnesium based alloy as World's strongest and lightest metal to change the world. Researchers from North Carolina State University have developed a material using magnesium which is light Novel Aqueous Processing of the Reverted Turbine-Blade A preliminary study on the hydrometallurgical recovery of rhenium from an engine-reverted superalloy, CMSX-4, was performed. The novelty of this work dealt with (i) the applicability of electro-generated Cl2 in rhenium leaching and (ii) the maneuvering of the organic extractants based on the metal speciation in leach liquor. In a two-step HCl leaching, more than 98%

4, which compares creep crack-growth rates for INCOLOY alloy 909 and INCOLOY alloy 903. The tests were conducted with fatigue-precracked specimens in air at 1000°F (540°C). INCOLOY alloy 903 is another low-expansion superalloy similar in composition to INCOLOY alloy 909.High-Temperature SuperalloysTherefore, the superalloys, which can resist high-temperatures, are strongly required. Both high manufacturability and high workability are demanded at the same time. In some applications, the wear resistance at high temperatures is also required. Co-based alloys properties as superalloys candidate (compared to Ni-based superalloys)
